Background: Radiation-induced glioblastoma (GBM) in patients previously treated for craniopharyngioma is a rare phenomenon. To the authors' knowledge, only seven cases have previously been documented in the literature.
Observations: Herein, the authors report a case of a patient presenting with a new diagnosis of multifocal GBM 15 years after having received adjuvant radiotherapy for a craniopharyngioma.
Glioblastoma (GBM) is the most common and aggressive primary adult brain tumor, with an estimated annual incidence of 17 000 new cases in the United States. Current treatments for GBM include chemotherapy, surgical resection, radiation therapy, and antiangiogenic therapy. However, despite the various therapeutic options, the 5-year survival rate remains at a dismal 5%.

While IHT is often associated with worse outcomes in emergent neurosurgical conditions, less is known about patient outcomes after IHT for urgent diagnoses such as brain tumors. We sought to evaluate patient outcomes after IHT for malignant brain tumor resection.

It is well known that there is cellular and microenvironmental heterogeneity within a single tumor mass. Thus, current established protocols for propagating tumor cells in vitro are limiting because resections obtained from conventional singular samples limit the diversity in cell populations and do not accurately model the heterogeneous tumor.

Methods: Patients undergoing surgical resection for cancer were selected from the Nationwide Readmissions Database (2010-2014). Multivariable analysis adjusted for patient and hospital level characteristics to ascertain the effect of depression on post-operative outcomes and 30-day readmission rates.
Background: Stereotactic radiosurgery (SRS) is indicated for a spectrum of brain tumors and is often an outpatient procedure, though severe disease may precipitate inpatient treatment. Readmission following inpatient SRS for brain tumors is not well understood.
Objectives: To characterize rate, associative factors, and predictors of SRS readmission.
Objective: Fragmentation of care following craniotomy for tumor resection is increasingly common with the regionalization of neurosurgery. Hospital readmission to a hospital (non-index) other than the one from which patients received their original care (index) has been associated with increases in both morbidity and mortality for cancer patients. The impact of non-index readmission after surgical management of brain tumors has not previously been evaluated.

As most developing countries have a limited fiscal space to support the program in the long run, the fiscal sustainability of UHC, such as that in Indonesia, relies heavily on the contributions of its members. The failure of a large proportion of voluntary enrollees/self-enrolled members/informal sector workers (Peserta Mandiri/Pekerja Bukan Penerima Upah [PBPU] members) to pay their premiums may lead to the National Health Insurance System (NHIS) in Indonesia being unable to effectively deliver its services.

Here, we demonstrate that constitutive extracellular signal-regulated kinase 1/2 (ERK1/2) activation sustains a stem-like state in glioblastoma (GBM), the most common primary malignant brain tumor. Pharmacological inhibition of ERK1/2 activation restores neurogenesis during murine astrocytoma formation, inducing neuronal differentiation in tumorspheres.

After initial treatment (index hospital), readmission to a different hospital (nonindex) can compromise quality of care, resulting in increased morbidity. We aimed to evaluate factors associated with nonindex readmission and evaluate association of nonindex hospital readmission on outcomes in patients with ruptured aneurysm.

Much interest has focused on identifying the properties of slow-cycling tumor cells in glioblastoma (GBM), the most common and lethal primary brain tumor. Despite aggressive ionizing radiation (IR) and treatment with the alkylating agent temozolomide (TMZ), GBM patients invariably relapse and ultimately succumb to the disease.

It remains unclear how fluid dynamics impacts tumor progression and can be targeted therapeutically. To address this issue, a novel telemetry-based approach was developed to measure changes in IFP during progression of GBM xenografts.
